Let's say you're on your second or third date and things are going well. You say, "hey, let's hangout at my place to watch Netflix". Make it as casual as possible. NOT something you say as the date ends.

Then I say the magic phrase that has worked for me: "You can come over as long as you promise no naughtiness".

She usually laughs and, most of the time, she accepts. This "promise" makes her feel more socially acceptable to go. She doesn't have to feel cheap because she's not going for that reason and you said that's not on the table.

But usually, naughtiness happens anyway. The right phrasing just makes it easier for her to accept.
